All the problems we have looked at in this chapter have assumed that all participants receive an equal share of what is being divided. Often, this does not occur in real life. Suppose Fred and Maria are going to divide a cake using the divider-chooser method. However, Fred is only entitled to 30% of the cake, and Maria is entitled to 70% of the cake (maybe it was a $10 cake, and Fred put in $3 and Maria put in $7). Adapt the divider-choose method to allow them to divide the cake fairly.
In the game Divider-chooser, as the name implies, one player, referred to as the dividers, divides S into two parts, and the other player, referred to as the dropdown, selects the share they desire while leaving the other share up for the spacer to decide.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
In our instance, Fred and Maria will share a cake in this way.
Without regard to the type of cake, they each prefer, Fred offers to split the cake into 10 equal pieces as the first option.
Maria, the chooser, got to pick any seven pieces to get her fair portion. Fred will get the final three pieces. Maria will have better options with this strategy because she is a picky person.

Prince Eric decided to go deep sea diving. He is 250 feet below sea level, and has has injured himself. He only has 10 minutes of air supply in his tank and can only rise towards the surface at a rate of 20 feet per minute. Ariel is trying to
get a replacement air tank. Due to Ursula's wickedness, she is forced to wait at 100 feet below sea level. Will Prince Eric be saved?
The depths below sea level, the rising speed, and the available air
supply, determine the minimum depth Ursula can wait.
Correct response;
Yes, he will be savedHow is the distance and time below sea level determined?The given parameters;
The initial depth of Prince Eric = 250 feet below sea level
Duration of air supply available = 10 minutes
Speed of ascent of Prince Eric = 20 ft./minute
The depth at which Ursula is forced to wait = 100 feet below sea level
The maximum ascent possible with the available air supply is given as follows;
Ascent = 20 ft./min × 10 min. = 200 ft.
Therefore, the air supply is insufficient to swim to the surface.
Level at which Ursula waits = 100 ft.
Level to which Prince Eric requires to ascent = 250 ft. - 100 ft. = 150 ft.
\(Time \ it \ takes \ to \ ascent \ to \ 150 \, ft. = \dfrac{150 \, ft.}{20 \, ft./min} = \mathbf{7.5 \,min}\)
The time it will take Prince Eric to ascend to Ursula's level is 7.5 minutes,
which is less than the 10 minutes, time to use the available air supply.
Therefore;
Prince Eric will reach Ursula before exhausting the air supply in his tank, and he will be saved.Learn more about calculations involving depths below sea level here:

Let z = 1 + 3i and w = -3 - 4i.
Use the drop down menus to complete the statements.
The sum z + w is equal to - -i
The sum w + z is equal to - 2 - i
The result supports that complex number addition is
Step-by-step explanation:
z+w= 1+3i-3-4i = -2-i
w+z=-3-4i+1+3i = -2-i
So, z+w = w+z
So, complex number addition is commutative
If z = 1 + 3i and w = -3 - 4i, then z + w = - 2 - i and w + z = - 2 - i, which supports that complex number addition is commutative.
What is commutativity property of addition?We are aware that the addition's commutative property states that altering the addends' order will not affect the sum.
How to solve it ?Here z = 1 + 3i and w = -3 - 4i.
Now, z + w = 1 + 3i - 3 - 4i = 1 - 3 + 3i - 4i = - 2 - i
and w + z = - 3 - 4i + 1 + 3i = - 3 + 1 - 4i + 3i = - 2 - i
i.e. z + w = w + z
Clearly, the addition obeys the commutative property.
Therefore we can conclude that If z = 1 + 3i and w = -3 - 4i, then z + w = - 2 - i and w + z = - 2 - i, which supports that complex number addition is commutative.

What is triangle?
A triangle is a closed, two-dimensional geometric shape with three straight sides and three angles.
To find the area of \($\triangle QRS$\), we can use the formula:
\($Area = \frac{1}{2} \times base \times height$\)
where the base and height are the length of two sides of the triangle that are perpendicular to each other. We can find these sides using trigonometry.
First, we need to find the length of side \($QR$\). We can use the Law of Cosines:
\($QR^2 = QS^2 + RS^2 - 2(QS)(RS)\cos(R)$\)
where \($R$\) is the angle at vertex \($R$\). Substituting the given values, we get:
\($QR^2 = 9^2 + 5^2 - 2(9)(5)\cos(57^\circ)$\)
\($QR \approx 8.02$\)
Next, we need to find the height of the triangle, which is the perpendicular distance from vertex \($R$\) to side \($QS$\). We can use the sine function:
\($\sin(R) = \frac{opposite}{hypotenuse}$\)
\($\sin(57^\circ) = \frac{height}{8.02}$\)
\($height \approx 6.51$\)
Now we can find the area of the triangle:
\($Area = \frac{1}{2} \times QR \times height$\)
\($Area = \frac{1}{2} \times 8.02 \times 6.51$\)
\($Area \approx 26.10$\) square units
Therefore, the area of \($\triangle QRS$\) is approximately \($26.10$\) square units.

Answer: any negative value
Step-by-step explanation:
g(x)= ax², inc on x<0 & dec on x>0
Firstly we need to get the derivative of g(x)
g'(x)=2ax
for inc interval g'(x) should be +ve
x<0 (i.e. x= -ve), then a must be -ve
for dec interval g'(x) should be +ve
x>0 (i.e. x= +ve), then a must be -ve
so in both cases a must be a negative constant

Step-by-step explanation:
What is the slope of the line that passes through the points ( 9 , 5 ) (9,5) and ( 21 , − 5 ) (21,−5)? Write your answer in simplest form.
Answer:
-5/6
Step-by-step explanation:
(9, 5) and (21, -5)
slope = m = (difference in y)/(difference in x)
m = (-5 - 5)/(21 - 9)
m = -10/12
m = -5/6
Answer: -5/6
The slope of the line that passes through points (9,5) and (21,-5) is -5/6.
We can use the two-point formula to find the slope for the given line. The formula is as follows:
(y2 - y1) = m*(x2 - x1)
Where (x1, y1, x2, and y2) represent the points on the line, and m is the slope of the line.
In the given case:
x1=9, x2=21
y1=5, y2=-5
Using these values in the two-point formula, we get:
(-5-5)=m*(21-9)
-10=m*12
m=-10/12
m=-5/6
Hence the slope of the line is -5/6.

1. Is it possible for the sequence t(n) = 5·2ⁿ to have a term with the value of 200? If so, which term is it? If not, justify why not.
2. Is it possible for the function f(x) = 5·2ˣ to have an output of 200? If so, what input gives this output? If not, justify why not.
Answer:
1) No,2) Yes, x ≈ 5.32-----------------------------
Part 1Given sequence:
t(n) = 5 · 2ⁿIf t(n) = 200, we can try to find the value of n:
5 · 2ⁿ = 2002ⁿ = 40There is no integer solution, since 32 < 40 < 64 or 2⁵ < 40 < 2⁶, the value of n should be between 5 and 6.
The sequence should include integer numbers, so there is no solution.
Part 2Given function:
f(x) = 5 · 2ˣSolve for x if f(x) is 200:
5 · 2ˣ = 2002ˣ = 40log 2ˣ = log 40x log 2 = log 40x = log 40 / log 2x = 5.32 (rounded)Answer:
1. No
\(\textsf{2.} \quad x=\dfrac{\ln 40}{\ln 2} \approx5.32\;(\sf 2\;d.p.)\)
Step-by-step explanation:
Question 1Given sequence:
\(t(n)=5 \cdot 2^n\)
To determine if the sequence has a term with a value of 200, substitute t(n)=200 into the equation and solve for n:
\(\implies 5 \cdot 2^n=200\)
\(\implies 2^n=40\)
\(\implies \ln 2^n=\ln 40\)
\(\implies n\ln 2=\ln 40\)
\(\implies n=\dfrac{\ln 40}{\ln 2}\)
\(\implies n=5.3219280...\)
In a sequence, n is a positive integer. Therefore, it is not possible for the sequence to have a term with the value of 200, as when t(n)=200, n is not a positive integer.
Question 2Given function:
\(f(x)=5 \cdot 2^x\)
To determine if the function has an output of 200, substitute f(x)=200 into the function and solve for x:
\(\implies 5 \cdot 2^x=200\)
\(\implies 2^x=40\)
\(\implies \ln 2^x=\ln 40\)
\(\implies x=\dfrac{\ln 40}{\ln 2}\)
\(\implies x=5.3219280...\)
Therefore, it is possible for the function to have an output of 200 when:
\(x=\dfrac{\ln 40}{\ln 2}\)

Calculate the missing angles a, b, c, and d in the diagram below, giving a reason for each answer
Answer:
see below and attachment
Step-by-step explanation:
a=30°
because, the marked angle of 30° is an alternate interior angle to angle a. Alternate interior angles are congruent, and we know they are congruent because the 2 horizontal lines are parallel.
b=50°
because the marked angle of 50° is a vertical angle to angle b. Vertical angles are congruent because 2 lines that intersect have opposite congruent angles, making them vertical angles to each other.
c=50°
because the marked angle of 50° is a corresponding angle (same side angle) to angle c. These corresponding angles are congruent because the 2 horizontal lines are parallel.
d=100°
because the 3 interior angles of a triangle must add up to 180°. We have 30°, 50°, so the last angle must be 100°. We can also figure this out because the bottom horizontal line is a straight line, meaning the angle is also 180°. We have angle a as 30°, angle c as 50°, so angle d must be 100°.

The sum of a number and 3 is less than or equal to 8
Answer:
m ≤ 5
Step-by-step explanation:
I will begin by assuming m to be the number.
Then, the sum of m and 3 is: m + 3.
The symbol for "less than or equal to" is ≤.
So we form an inequality, like this :
m + 3 ≤ 8
To find m subtract 3 on each side:
m ≤ 5
Therefore, m ≤ 5.
